What were your troubleshooting steps?
------------------------------------------------------------------------
From the Active BIGIP, to verify routing:
-Are you able to successfully ping the SMTP server?
-Did you try a "port knock" test via the telnet command on port 25 and 587, to ensure routing and the port is open on the SMTP server?
-Do you have a SELFIP on the same subnet & VLAN as the SMTP server and/or a Default Route configured?
Yes, there are communication between the F5 and the servers. the pools comes up with TCP or ICMP and etc but not with TCP port 587. The virtual server has being working fine on port 25 until a new requirement for secure communication between the F5 and the servers. The servers are lsiten on secure SMTP. My objective is to setup secured SMTP virtual server for the servers and to enable secure end to end communication. I am not sure if the F5 virtual server will actual work without the health monitor being port 587. I having problem setting up custom health monitor with TCP port 587 and that is what I am requesting for help for anyone who know how to setup secured SMTP virtual server and health monitor.
